great for the price and reliable
to get the most out of these speakers they definitely need to be used with a good quality amp and a sub is a must. With properly set gain these sound clear the tweeters are bright but after some time they soften up. I have mine getting 50 watts rms gain on the amp set with a multi meter. Alpine hu bass 0 mid -1 treble +1 Overall a pretty good set for the price. I would not run them off a cheap or low quality factory hu or without the use of a sub. Dropped a star because IMHO the tweeters could be a little better. The gauge speaker wire they put on the tweeters are ultra thin. They require a significant amount of break in time before they soften up. I used to go negative on the treble when I first got them but could of been up too high on the gain on my amp when I first installed them. I've had them roughly 8 years so they hold up well.
Pros: price,hold up well
Cons: not the softest sounding tweeters but do get better with time
